[0032] In the description of the embodiments of the present application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0033] This application embodiment provides a ceiling machine, please refer to Figure 1The ceiling machine includes a water tray installation assembly 10.

[0034] See also Figure 2 The water tray installation assembly 10 of the embodiment of the present application includes a housing 11 , a foam member 12 and a water tray 13 .

[0035] The outer shell 11 includes a chassis 111 and a surrounding plate 112 arranged around the chassis 111, the chassis 111 and the surrounding plate 112 jointly define a accommodating cavity 11a having an opening 11a1, the foam piece 12 has a hollow area 12a, the foam piece 12 is arranged in the accommodating cavity 11a, the hollow area 12a is connected to the opening 11a1, wherein the foam piece 12 has a first side X1 close to the surrounding plate 112 and a second side X2 opposite to the first side X1, the water receiving tray 13 is arranged in the hollow area 12a, and the water receiving tray 13 is in contact and connected with the portion of the foam piece 12 located on the second side X2.

[0036] The accommodating chamber 11a is used to accommodate the foam member 12 and other components. The foam member 12 is used for heat insulation.

[0037] The outer shell 11 may be wrapped around the outer periphery of the foam member 12 to ensure the heat preservation of the foam member 12 and prevent condensation from occurring on the outer shell 11 .

[0038] The hollow area 12 a of the foam member 12 is used to accommodate the water receiving tray 13 .

[0039] See also Figure 5 The first side X1 is close to the enclosure 112, that is, the first side X1 refers to the outer peripheral side of the foam piece 12, and the second side X2 is the inner side of the foam piece 12, that is, the side close to the hollow area 12a.

[0040] The water receiving tray 13 is in contact with and connected to the foam member 12 at the second side X2, that is, the portion where the water receiving tray 13 is connected to the foam member 12 is located on the side of the foam member 12 facing away from the enclosure 112, or in other words, the outer surface of the foam member 12 at the first side X1 blocks the portion where the water receiving tray 13 is connected to the foam member 12.

[0041] Contact connection means that the water receiving tray 13 and the foam member 12 are connected in a direct contact manner, that is, no intermediate member such as a sponge is provided between the connection portion of the water receiving tray 13 and the foam member 12 .

[0042] Please continue reading Figure 1 The ceiling machine is generally provided with a panel assembly 20, an air guide ring 30, a fan assembly 40, a heat exchanger 50, a drainage structure 60 and an electric control box 70.

[0043] Among them, the panel assembly 20 is arranged at the opening 11a1 of the shell 11 and is connected to the shell 11. The panel assembly 20 has a return air area and an outlet air area. The airflow enters the ceiling machine through the return air area, and after heat exchange inside the ceiling machine, it flows out from the outlet air area.

[0044] See also Figure 2 , the water receiving tray 13 can be provided with a return air port 13a. Preferably, the return air area can be connected to the return air port 13a to ensure the working effect of the ceiling machine.

[0045] The heat exchanger 50 is located in the hollow area 12a of the foam member 12. For example, see Figure 1 The heat exchanger 50 can be bent to form a return air space. The heat exchanger 50 and the foam member 12 are spaced apart to form an air outlet channel at the interval. The return air space is connected to the return air port 13a of the water receiving tray 13. The external air flows into the return air space through the return air port 13a for heat exchange and then flows out from the air outlet channel.

[0046] The fan assembly 40 includes a wind wheel 41 and a driving motor 42. The fan assembly 40 is arranged in the return air space of the heat exchanger 50 and is connected to the chassis 111 to introduce the external airflow from the return air area of ​​the panel assembly 20 into the ceiling machine, and blow the airflow after heat exchange out from the air outlet area of ​​the panel assembly 20 through the air outlet channel.

[0047] The air guide ring 30 is disposed at the air return port 13a of the water receiving tray 13 to guide air.

[0048] The electric control box 70 is used to control the operation of the ceiling machine. Exemplarily, the electric control box 70 can be arranged on a side of the air guide ring 30 away from the chassis 111.

[0049] The drainage structure 60 includes a water pump 61 and a drainage assembly 62 . The drainage structure 60 may be disposed on the housing 11 to drain the condensed water in the water receiving tray 13 .

[0050] For example, see Figure 1 , Figure 5 and Figure 5 The water receiving tray 13 may also include a drainage portion 134 having a drainage area, the foam piece 12 has a first avoidance port 12e connected to the hollow area 12a, the enclosure 112 has a second avoidance port 112b connected to the first avoidance port 12e, the drainage portion 134 is in contact with the foam piece 12, and the drainage area is connected to the outside through the first avoidance port 12e and the second avoidance port 112b.

[0051] The drainage area is used to receive condensed water in the water receiving pan 13. The condensed water is led out of the water receiving pan 13 by the drainage structure 60 in the drainage area. By providing the first avoidance opening 12e on the foam member 12 and the second avoidance opening 112b on the enclosure 112, the drainage structure 60 can facilitate the drainage of condensed water.

[0052] In the related art, the installation method of the water receiving tray is generally to set a mounting notch on the side of the foam piece close to the opening of the shell, the mounting notch runs through the opposite sides of the foam piece, and the part where the water receiving tray and the foam piece are connected (referred to as the connecting part) is located in the mounting notch. At the same time, the connecting part of the water receiving tray and the foam piece are sealed by setting a sponge. However, the sponge generally needs to be pasted on the foam piece, which is time-consuming. If the pasting is not good, it is also easy to cause condensation on the enclosure of the shell due to the poor sealing between the connecting part and the foam piece.

[0053] The water receiving tray installation assembly 10 of the embodiment of the present application is to set the water receiving tray 13 in the hollow area 12a of the foam part 12, and the water receiving tray 13 is in contact and connected with the part of the foam part 12 located on the second side X2, that is, the part where the water receiving tray 13 is connected to the foam part 12 is located on the side of the foam part 12 away from the enclosure 112, and the foam part 12 is not provided with an installation notch. Therefore, the foam part 12 has good sealing and heat preservation properties. The water receiving tray 13 and the foam part 12 only need to be in contact and connected to meet the sealing requirements. Since there is no need to arrange a sponge between the two, the assembly efficiency of the water receiving tray installation assembly 10 can also be improved.

[0054] In addition, regarding the installation method of setting a sponge in the related art, since the sponge has a certain thickness, during the installation of the water receiving tray, the sponge can easily lift up the water receiving tray, causing the water receiving tray to be suspended in the air. Therefore, after the water receiving tray is installed, the sponge may not be completely compressed, causing a local area of ​​the water receiving tray to be lifted up by the sponge and deformed.

[0055] However, the water receiving tray 13 and the foam member 12 of the embodiment of the present application are in contact connection, and there is no need to arrange a sponge between the water receiving tray 13 and the foam member 12. Therefore, the water receiving tray 13 will not be lifted up by the sponge and deformed.

[0056] In one embodiment, please refer to Figure 3 The foam piece 12 has a first end face 12b located on the side of the hollow area 12a near the opening 11a1, and the enclosure 112 has a second end face 112a located on the side of the opening 11a1. The height difference between the first end face 12b and the second end face 112a can be 0mm to 5mm (including the endpoint values).

[0057] That is to say, the first end face 12b and the second end face 112a can be flush with each other (that is, the height difference between the first end face 12b and the second end face 112a is equal to 0 mm), and the first end face 12b and the second end face 112a can also have a certain height difference, but the first end face 12b is roughly flush with the second end face 112a to ensure the sealing and thermal insulation of the water tray installation assembly 10.

[0058] In one embodiment, the water receiving tray 13 is provided with one of the mounting block 132 and the mounting groove 12c, and the second side X2 of the foam piece 12 is provided with the other of the mounting block 132 and the mounting groove 12c. The mounting block 132 and the mounting groove 12c are snap-fitted to achieve contact connection between the water receiving tray 13 and the foam piece 12.

[0059] The water receiving tray 13 and the foam member 12 are connected by snap-fitting the mounting block 132 and the mounting groove 12 c, which can improve the assembly efficiency of the water receiving tray mounting assembly 10 .

[0060] See also Figure 2 and Figure 3 The mounting block 132 may be a hollow structure to facilitate airflow and facilitate the lightweight design of the water tray mounting assembly 10 .

[0061] The number of the mounting blocks 132 may be multiple, and the mounting grooves 12c correspond to the mounting blocks 132 one by one. For example, see Figure 2 To ensure the connection stability between the water receiving tray 13 and the foam member 12 , the number of the mounting blocks 132 may be three, and the number of the mounting grooves 12 c may also be three.

[0062] In other embodiments, one mounting groove 12c and one mounting block 132 may also be provided.

[0063] For example, see Figures 2 to 5 The foam member 12 has a mounting groove 12c, and the water receiving tray 13 may include a tray body 131 and a mounting block 132 arranged on the outer peripheral side of the tray body 131, and the tray body 131 is used to accommodate condensed water.

[0064] The mounting groove 12c is located at the second side X2 of the foam member 12, that is, the side of the mounting groove 12c away from the second side X2 has a groove wall, and the mounting groove 12c does not penetrate the foam member, thereby enhancing the sealing performance of the foam member.

[0065] Part of the first end surface 12b is recessed in a direction away from the opening 11a1 to form a mounting groove 12c communicating with the hollow area 12a. In another embodiment, the foam member 12 may have a mounting block 132 and the water receiving tray 13 may have a mounting groove 12c.

[0066] That is to say, the installation groove 12c is formed by a partial area of ​​the first end surface 12b being recessed in a direction away from the opening 11a1, and the installation groove 12c is connected to the hollow area 12a, which can facilitate the installation block 132 to be inserted into the installation groove 12c from the opening 11a1.

[0067] The mounting block 132 may be placed against the bottom wall of the mounting groove 12 c to further ensure the installation stability of the water receiving tray 13 .

[0068] The installation position of the installation groove 12c is not limited. For example, please refer to Figures 2 to 5 The foam member 12 may have a plurality of corner portions 121 located around the hollow region 12a, each corner portion 121 is provided with a mounting groove 12c, and the mounting blocks 132 correspond to the mounting grooves 12c one by one.

[0069] That is, the installation groove 12c is arranged at the corner portion 121 of the foam member 12. The corner portion 121 has good structural strength, and the installation groove 12c is arranged at the corner portion 121, which can reduce the deformation of the foam member 12 caused by the water receiving tray 13.

[0070] See also Figure 2 and Figure 3 A portion of the mounting block 132 is inserted into the mounting groove 12 c , and on a projection plane parallel to the opening 11 a 1 , the projection dimensions of the mounting block 132 gradually shrink in a direction away from the foam member 12 .

[0071] A portion of the mounting block 132 is inserted into the mounting groove 12c. At the same time, since the mounting block 132 is arranged on the outer peripheral side of the disk body 131, when the mounting block 132 is installed in the mounting groove 12c, the disk body 131 and the foam piece 12 are spaced apart so that the airflow in the air outlet channel can flow out.

[0072] The projected outer dimensions of the mounting block 132 gradually shrink in a direction away from the foam member 12 , so that the structural stability of the water receiving tray 13 can be improved.

[0073] In one embodiment, please refer to Figures 3 to 5 A partial area of ​​the first end surface 12b can be recessed in a direction away from the opening 11a1 to form a fixed groove 12d connected to the mounting groove 12c. The water tray mounting assembly 10 also includes a mounting ear 14 and a fixed block 133 arranged on the mounting block 132. The fixed block 133 is inserted into the fixed groove 12d. The mounting ear 14 is arranged on the outer side of the enclosure 112 and is connected to the fixed block 133.

[0074] The mounting ear 14 is fixed to the outer side of the enclosure 112 , and the fixing block 133 is connected to the mounting ear 14 , which can further enhance the connection stability between the water receiving tray 13 and the foam member 12 .

[0075] For example, see Figure 3 and Figure 4 The mounting ear 14 has a mounting folded edge formed by bending, and the mounting folded edge extends into the fixing groove 12d and is connected to the fixing block 133. That is to say, the mounting folded edge and the fixing block 133 are both located in the fixing groove 12d, and the fixing block 133 is connected to the mounting folded edge in the fixing groove 12d, thereby improving the installation stability of the water receiving tray 13.

[0076] See also Figure 5 The distance from the first end face 12b to the bottom of the fixing groove 12d can be smaller than the distance from the first end face 12b to the bottom of the installation groove 12c, that is, the depth of the fixing groove 12d is smaller than the depth of the installation groove 12c. The stepped shape formed thereby can prevent airflow from overflowing and causing condensation on the enclosure 112.

[0077] To further ensure the sealing performance, the groove width of the installation groove 12 c may be greater than the groove width of the fixing groove 12 d . Accordingly, the outer dimensions of the projection of the installation block 132 are greater than the outer dimensions of the projection of the fixing block 133 .

[0078] Please continue reading Figure 5 The fixing groove 12d can be located on the side of the installation groove 12c away from the hollow area 12a to facilitate the connection between the installation ear 14 and the fixing block 133, and at the same time is beneficial to the sealing of the water tray installation assembly 10.
